Hey, n00b, is there a way I can merge two mkvs from a certain frame with MKVToolNix? For example, open a mkv, then add a second mkv right after frame 2000 of the first mkv, and that includes the audio. Because I'm spending a lot of time googling how to do this...
I never needed such a function but have you already tried the "append" button (next to the "add" button)?
